Phytochemical Analysis and Antimicrobial Potential of Parthenium hysterophorous and Lantana camara.

Abstract

Background: Parthenium hysterophorous and Lantana camara are notable for their significant phytochemical and antimicrobial properties. Advancements in phytochemical research have led to the development of novel formulations and products derived from P. hysterophorus and L. camara. For instance, patent extracts from these plants have been utilized in the formulation of pharmaceutical drugs, herbal supplements, cosmeceuticals, and agricultural products. P. hysterophorous, commonly known as Santa Maria feverfew or Congress grass, contains various bioactive compounds like terpenoids, flavonoids, phenolics, and alkaloids.These compounds are the key to its medicinal properties, particularly its antimicrobial activity. On the other hand, L. camara, often referred to as wild sage, is rich in phytochemicals such as terpenoids, flavonoids, and alkaloid glycosides.

Methods: P. hysterophorous and L. camara plants selected and checking their antimicrobial activity by agar well diffusion method.

Results: In our study, we found that the leaf extract of P. hysterophorous exhibited the most potent antibacterial activity against E. coli. P. hysterophorous exhibited the most potent antifungal activity against A. niger and T. viride, with a diameter of inhibition zone measuring 12 mm, followed by A. flavus and A. parasiticus. In case of L. camara, the inhibitory zone ranging from 14 to 18 mm was detected against S. abony, P. aeruginosa, E. coli, and K. pneumonia. The leaf extract of the maximum zone of inhibition in case of L. camara was shown by A. flavus (12mm).

Conclusion: The present study suggests that these two weeds could be useful in the development of bactericides and fungicides.
